Control method of cultivated soil monitoring system

Abstract

The invention discloses a control method of a cultivated soil monitoring system. The soil monitoring system comprises a soil monitoring module, a wireless transmission module, a control module, a display module and an alarming module, wherein the soil monitoring module comprises a plurality of soil monitoring units; the soil monitoring units comprise a temperature sensor, a GPS (Global Positioning System) positioning unit, a humidity sensor, a soil pH (Potential of Hydrogen) sensor, a heavy metal electrochemical sensor array, a heavy metal signal adjusting circuit and a microcontroller. In a working process, the control module is used for controlling the display module to display soil quality information of each soil monitoring unit; and when a heavy metal concentration is higher than a pre-set heavy metal concentration threshold value or the soil pH is not in the soil quality information with the pre-set heavy metal concentration threshold value range, the display module is controlled to distinctly display the soil quality information and alarming module is controlled to alarm. The soil monitoring system is simple in structure and can be used for reflecting the concentration of cultivated soil pollutants in real time.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a control method for an agricultural soil monitoring system. Background technique [0002] Soil refers to the loose surface layer on the land surface that is fertile and capable of growing plants, and its thickness is generally about 2 m. Soil not only provides mechanical support for plant growth, but also provides fertility elements such as water, fertilizer, air, and heat for plant growth and development. Due to the rapid growth of population and the rapid development of industry, solid wastes are continuously stacked and dumped on the soil surface, harmful waste water is continuously infiltrated into the soil, and harmful gases and floating dust in the atmosphere are also continuously falling into the soil with rainwater, resulting in soil pollution. All substances that hinder the normal function of the soil, reduce the yield and quality of crops, and indirectly affect human h...

Problems solved by technology

[0005] Traditional soil pollution monitoring is mainly based on manual sampling and laboratory instrument analysis, which has the disadvantages of low monitoring frequency, small monitoring range, large sampling error, and poor real-time performance.

[0006] The traditional soil pollution monitoring system lacks the technical means for real-time dynamic collection and analysis of air pollution data in a large area, and it is easy to miss the best period for timely prevention and control in the early stage of pollution
